Background. Streptomycetes were and remain a source of new antimicrobial compounds various nature. A wave interest in such research is associated with the possibilities applied genomics to reveal hidden biosynthetic potential streptomycetes, therefore discovery practically valuable products. The problem antibiotic resistance pathogens can be solved by creating compositions active substances dif...

It is common knowledge the current trend of developing and testing products accrued from natural plants. On that premise, Stryphnodendron adstringens (Mart) Coville highlighted was aim for evaluating its antibacterial effect on dental caries. A crude dried methanolic extract prepared applied 50 to 500 mg/mL determine Minimum Inhibitory Concentration (MIC) seven distinguished bacterial cultures....

A 40% rumen fluid basal medium has been developed that without added substrate will support growth of about 10% or less of the total colony count obtained with 40% rumen fluid-glucose-cellobiose-starch-agar medium (RGCSA). The basal medium is prepared by anaerobic incubation of all ingredients in RGCSA medium except the carbohydrates, Na2CO3, and cysteine for 7 days at 38 degrees C. After incub...
